Subject: [ANNOUNCEMENT] [1.7] Updated: {terminfo0/terminfo0-extra}-5.5_20061104-11

The terminfo0 packages contain the terminal information database that
enables proper operation of ncurses-based applications. This package,
which can be installed alongside the regular 'terminfo' ones, provides
that database using the organizational structure expected by libncurses8
and earlier (newer ncurses applications, using libncurses9 and newer,
use a different structure on cygwin, correcting issues with case-
sensitivity).

The current terminfo, in order to improve operation on case-insensitive
platforms, is now organized according to the two-digit hexadecimal code
of the entry's first letter, instead of organized according to that
first letter itself.  For instance:

  OLD (terminfo0) --->   CURRENT (terminfo)
  r/rxvt-unicode         72/rxvt-unicode


Each database is actually provided in two parts. The terminfo0 package 
provides most of the terminal definitions commonly used on the cygwin
platform, and a selection of others. The terminfo0-extra package provides
all of the others (again, arranged using the "old" libncurses8-compatible
organization).

In addition, because (a) the libncurses8-based tic0 tool must be used
to generate the old-style database, and (b) that old tic0 tool cannot
support some constructs in the new 5.7_20091114 terminfo.src file, the
terminfo0 database is "stuck" at an old version (5.5_20061104) of the
terminfo.src, and as such may contain bugs in the terminal definitions
it supplies. The fix for client applications is to recompile against
libncurses9 and thus use the current terminfo packages, rather than
continuing to rely on this old and possibly broken terminfo0 package.


CHANGES (since 5.5_20061104-2)
========================
o Modify screen, xterm, cygwin, and cygwin-DBG terminal
  types to use ^? for backspace (e.g kbs=\177) rather than
  ^H.  Screen and the cygwin-1.7 console use this setting
  by default, so this corrects an error in the terminfo data.
  xterm has not yet been updated to use ^?; you should modify

        /etc/X11/app-defaults/XTerm

  and add the following two lines, until it is updated:

        *backarrowKeyIsErase: true
        *ptyInitialErase: true
